Administration officials offered The Back Chanel more tips on moves afoot in the Obama administration foreign policy team.

In the certain to go camp:

Assistant Secretary of State for Asia and Pacific Affairs Kurt Campbell is leaving, official told the Back Channel, to chair the board of the Center for New American Security (CNAS), the think tank he co-founded with Michele Flournoy, and do Asia consulting. (His spouse Lael Brainard, Under Secretary of Treasury for International Affairs, may leave the administration too, an official said. White House chief of staff Jack Lew is expected to succeed Tim Geithner as Treasury Secretary.)

NSC Middle East senior advisor Steve Simon is due to leave shortly to become head of a think tank, officials told the Back Channel.

AfPak envoy Marc Grossman will leave, officials said. It is unclear who will succeed him.

In the likely to move camp:

Deputy Secretary of State William Burns may be nominated to succeed Rice as US ambassador to the UN, officials said.

Deputy Secretary of State Tom Nides is being mulled for a White House job, possibly White House chief of staff, which can put his knowledge of budgets to work, as well as his relationship with Congress and Wall Street.
